UNITED STAT Es PATENT OFFICE This invention relates to an electricrazor, the general object of the invention being to provide meanswhereby the comb orguard of the razorn will move whereby the razor isprovided with a movable blade operating over a, movable guard or combwhich, in effect, provides movable cutting members for each hair isengaged by a portion of the blade edge and a wall of an opening in thecomb.

Another object of the invention is to provide means whereby differentportions of a comb can be used to suit the type of'beard being cut.

- Another object of the invention is to provide means whereby the bladeand comb will move in diiferent directions.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

Referring to Figures 1, 2, 3, 4, 5 and 6, the body of the razor is shownat A and the electric motor is shown at a in dotted lines in Figure 2,the shaft driven from the motor being shown at I and said shaftat itsouter 'end is formed with the head 2 carrying the eccentric 3 whichengages between the spaced plates 4 on the blade carrying head 5 whichis rotatably arranged on the shaft Shaving its ends journaled in thecaps 1 in theside members 8 of the casing'part of the body A, these sideparts 8 being slightly flexible, as

shown in dotted lines in Figure 4 so that by spreading them apart thehead 5 with the comb member B can be removed. The outer ends of theseparts 8 are rounded as shown in Figure 1 and these partsaresubstantiallyV ilat and an opening isformed in the casing between partsI as shown in Figures 2 and 3, the shaft I extending into this openingwith the parts 2, 3, 4, I and 8, lying in the opening. The blade 9 ts ina groove in the head 5 and is held therein by a screw I0 or otherfastening means and the outer end of the blade is hollow ground so that4it will be self-sharpening in the usual manner. Of course, as will beseen from Figure 3 when the shaft I is rotating the eccentric l-willcause the head I to rock on the shaft Gand thus the blade 9 isoscillated. 'Ihe comb member includes the substantially semi-cylindrical.part `I0-havlng its ends connected to the side parts II of the yoke I2,the bight of the yoke having an opening Il therein which receives theeccentric I4 on the shaft I so that as the shaft I rotates the eccentricI4 will rock the comb member B on the shaft 8, the side parts Il of thecomb member being journaledon end portions of said shaft as shown inFigure 4.

Thus it will be seen that when the shaft I is a being rotated by themotor the blade 9 will be oscillated and the comb member will also beoscillated so that the part I0 of the comb which has the openings IIItherein will move relative to the blade, the cutting edge of the bladebeing in contact with the inner wall of the part I0 in the usual manner.'I'hus the walls of the openings III' form movable cutting edges withthe cutting edges of the blade so that the cutting of the hairs of thebeard is greatly facilitated.

By having the opening passing through the casing inwardly of the comb I0the cut hairs and other matter passing through the openings I 0' will bedischarged from the razor and will not accumulate therein so that therazor is practically self-cleaning. While .the drawings show theopenings I' in the form of holes it is to be understood that they may bein the form of slots v to suit practically all types of beard and alsofor or if desired both holes and slots can be used.

In that form of theinvention shown in Figures '1, 8 and 9, the cuttingmember is of the rotary type and includes a square shaft I5 having re'duced cylindrical ends I6 which are Journaled in the caps I1 carried bythe side members I8 of the casing and curved blades I9 are attached tothe four sides of the shaft I5 by the screws 20 and a curved spring 2|engages each blade and tends to hold it in cutting position or with itshollow cutting head in engagement with the inner wall of the comb memberB'. This comb member is in the shape of a cylinder and is composed offour sections, two of the opposed sections having the slots 22 thereinand the other two sections having the holes 23 and if desired theseholes and slots of one section may be of different sizes from those ofthe opposed sections and the parts are so arranged that the blades I3will onlyengage the inner wall of each section when the section is inits forward or operative position as shown in Figure 8. 'I'hecylindrical comb member B vis provided with end pieces 24 which haveholes therein for the passage of the trunnions I5 and the cylindricalpart is formed with small enlargements 25 at its ends which fit overthese end pieces and the cylindrical part is also formed with a centralrib 26 which extends circumferentially and acts to reinforce thecylinder. Each section also gradual- 1y decreases in thickness from itsside edges to its center as shown in Figure 8. A transverse shaft 21 isjoumaled in the side pieces I8 of the casing and is driven by wormgearing 28 from .the motor shaft 29 which is arranged at an angle andthat part of the casing which carries the operating means extends at anangle from the rest of the casing as shown more particularly in Figure12. A gear 30 is connected to one end of the shaft 21 and meshes with agear 3| keyed to one of the trunnions I5, as shown in Figure 9 andlocated between an end member 24 and a side member I3. Thus the rotaryblade assembly is rotated from the shaft 21 through means of these gears30 and 3|. The adjacent end member 24 is not connected with thecylindrical part but loosely ts in the enlargement 25. A

wide and tapered arm 35 has its large part fitting between the othermember 24 and the adjacent piece I3 and this arm 35 is removablyconnected with the adjacent end member 24 by the pins 36 fitting inholes in the member 24. The arm extends rearwardly and has a notch 31 inits small inner end which ts over an eccentric 33 on the shaft 21 sothat the comb member B is oscillated or rocked by the eccentric 38. Aswill be seen the comb member is rocked by the shaft 21 as the cutterassembly is being rotated bythe gearing from the shaft 21 and the partsare so arranged that only one section of the cylindrical part of thecomb member will be engaging the face during the rocking movement. Bypressing the end members I8 away from each other the parts can beremoved as before described and the comb member can be adjusted to placea new section in operative position so that the user can use a sectionhaving the slots 22 therein or a section having the holes 23 therein andas before stated by making the hole carrying parts of diiferent sizesand the slot carrying shaving close or not so close.

Figures 11, l2, 13 and 14 show an arrangement whereby the comb member B"is rotated instead of rocked and this is done by providing a large gear40 connected with one end of the comb member and engaged by an idlepinion 4I attached to one of the side members of the casing and whichidle pinion is engaged by a pinion 42 on the shaft 21 which carries thegear 43 engaging the gear It attached to the blade carrying shaft 45which has the slots t6 therein for slidingly receiving the inner ends ofthe straight blades 41 which have their cutting edges pressed againstthe inner walls of the cylindrical comb member by the leaf springs 48 inthe slots of the shaft d5.

Thus the combv cylinder is rotated in one direction and the bladeassembly in an opposite direction and this cylinder may be provided withthe slots or holes or a combination of both. Preferably in use of thistype of invention the comb cylinder is held against the face and rotatesin an upward direction which forces the hair into the holes or openingswhile the blade assembly rotates in the opposite direction. As will beseen the rotating comb acts to pull the hairs into the openings and theblades of the rotating shaft cut the hairs oi.

In this form of the invention the shaft 21 is also driven by wormgearing from the motor shaft and the parts can be removed by spreadingthe ends or side members I 8.

Figures 15, 16, 17, 18 and 19 show a modified form of cylindrical combwhich is to be oscillated in any suitable manner and which is to besupported so that it can be adjusted to bring any one of the foursections 50, 5I, 52 or 53 into operative position to engage the face. Aswill be seen section 50 is formed with holes, section 5I with straightslots. section 52 with angle slots and section 53 with spirally arrangedslots and .the edges of these slots are beveled to provide cutting edgesas shown at 54 in Figure 19. Also, and as will be seen, the center rib55 does not extend over section 53 which has the spiral slots therein.

I have found that these spiral slots enable the razor to cut. closerthan with other types of openings so that one does not have to shave asoften and these spiral slots can also be used with the half cylindricalcomb shown in Figures 1 to 6.

The central ribs in all forms of the invention are provided with slotsand they are of such small size as to not interfere with the shavingoperation and these spiral slots can also be used with that form of theinvention shown in Figures 7, 8 and 9.

The wall parts of the cylinder are formed, as shown in Figure 8, forinstance. so as to add strength to the cylinder while enabling parts tobe made so thin as to enable one to secure a close shave with thedevice.

It is thought from the foregoing description that the advantages andnovel features ofthe invention will be eadily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.
